Title: Production of maleate copolymer
Inventor: FUKUMOTO YASUHISA
IPC: C08F222/02
Filed: 1984-04-06
Abstract: PURPOSE:To produce the titled polymer having an average MW within a specified range in good efficiency, by adding a specified monomer to a monoalkali metal or monoammonium salt of maleic acid and polymerizing the mixture in an aqueous solvent. CONSTITUTION:An alkali metal hydroxide or ammonia water is added to an aqueous solution of maleic acid (anhydride) to form a monoalkali metal salt or a monoammonmium salt. The formed aqueous solution is mixed with 5mol, per 100mol of maleic acid, or below, of a monomer selected from the group consisting of (meth)acrylic acid, itaconic acid, acrylamide, allylsulfonic acid, etc., and a polymerization initiator, and the mixture is polymerized at 80-180 deg.C.

Patent JP-H05276034-A (JP)
Title: Digitizer
IPC: H03M1/10
Filed: 1992-03-26
Abstract: PURPOSE:To obtain the digitizer able to detect production of aliasing by comparing a frequency of an original input analog waveform with a frequency of the original input signal after it is A/D-converted and then D/A-converted. CONSTITUTION:Suppose that a period of a sampling clock is very close to or delayed than a period of a signal to be measured and the result of occurrence of aliasing is observed, then an output (e) of a D/A converter 12 has a very slower frequency than the frequency of the amplified signal (a) to be measured. Thus, the frequency of an output (g) of a toggle circuit 6 is very slower than the frequency of an output (c) of a toggle circuit 9. Since an enable period for a counter 10 is long and lots of leading edges of clock signals are in existence for the period, the count of the counter 10 indicates 2 or over. Then a discriminator 11 discriminates the count, a display controller 4 is used to display an error message on a screen of a display device based on the signal outputted from the discriminator 11 or an alarm tone is raised from a measurement main body controller.

Title: Analog/digital hybrio simulator
Inventor: MIZUTANI TORU
IPC: H03M1/12
Filed: 1991-03-10
Abstract: PURPOSE:To reduce a time required for conversion by providing two kinds of threshold levels to a 1-bit A/D converter. CONSTITUTION:A different threshold level is adopted for the case that a digital signal is converted to '1' and the case that a digital signal is converted to '0'. That is, when an analog waveform V crosses a threshold level from a lower level to an upper one and a digital signal changes from '0' to '1', the threshold level 01 is selected and when an analog waveform V crosses a threshold level from a higher level to a lower one and a digital signal changes from '1' to '0', the threshold level 10 is selected. Since the levels V01, V10 differ from each other, A/D conversion is implemented and even when a change in the analog quantity in the case of upper to lower change within a range of the analog values V10 and V01, number of times of the conversion into a digital value is reduced, then the required time of A/D conversion is reduced. Thus, the conversion to the digital value is implemented accurately.

Abstract: PURPOSE: To provide a switching device for a LAN in which the delay of a packet is reduced. CONSTITUTION: When the packet is received by a port reception part 1, it is stored in a reception buffer 6 by a reception buffer storage part 2. The reception buffer storage part 2 reports the storage address of the packet to an address filter part 7.

Moreover, it is recognized to which port a terminal with what address should be connected by registering the information of the transmission origin address and a reception port on the address table. Thence, the storage address of the packet and the information to which port it should be sent out are reported to a transmission buffer storage part 3.  The transmission buffer storage part 3 transfers them to the port transmission part 4 of the port to which the packet should be sent from the storage address. The port transmission part 4 transmits the packet to an Ethernt (R) by a transmission system selected by a control signal from a control part 5.
